Ronna and Beverly are Jessica Chaffin and Jamie Denbo, two American "thirtysomething" actors playing "fiftysomething" Jewish mothers who have co-authored abook of relationship advice called "You'll Do Better Next Time". But the duo aren't just self-help authors, they also fancy themselves as chat-show hosts and their guests have previously included Matthew Perry and Russell Brand. Matt Lucas is tonight's guest star and, though he has appeared before, his changeable expression seems to mirror the uneven ride that Ronna and Beverly take their audience on over the hour.

They were once "two idiots dancing toward a canyon" and tonight Russell Brand, who coined that phrase on his last live tour, and Jonathan Ross were reunited publicly for the first time since Sachsgate.
